I've tracked my leak down to this hose, I'm going to replace it, but I don't know what it's called to order my new one.

The one circled in red in the first picture:

 

That, sir, looks to be the ol' 964-207-254-07 (formerly the ol' 964-207-254-04).

(but others should correct if I'm wrong.)

...and sorry about that price. As I've been aided recently, try Sunset for a price break.

 

#46 in this pic? It's about 300 bucks on Pelican. Here. Oops. Photo a bit big...

 

Wow, good thing it's not expensive, haha. I'll look a little better and make sure that's what's leaking before I do anything drastic. Thanks a lot for the quick replys.

 

Wait until you try and replace it...it's a real pain in the rear to get in/out without completely removing the oil tank.

 

#46 correct. I just ordered one from Sunset Imports (http://sunsetporsche.com/porsche.php). The price was a bit lower than Pelican.

 

Oh great!...

 

A fix worth doing! Think of this hose as an artery...

The problem I encoutered was the coupling btw the new hose and the thermostat thingy. New washers are recommended! Also, I didn't torque it down initially, instead I played with it until it didn't have anymore micro-leaks.

 

Oil Pipe part number is now: 964-207-254-08 - US$275.71 from Sunset imports. Arrived today.
Hose clamp: 999-511-087-02 - US$2.24 from Sunset imports. Arrived today.

I got two set of seal rings... one for the adapters and one for the plugs

Seal ring (same one used in the front cooler): 900-123-139-30 - US$0.52 from Sunset imports. Arrived today.

Seal ring (for the plug on the top behind the oil filter, this is the one to drain the oil filter before removing): N0138132 -US$1.00 (this one I had ordered from Pelican Parts sometime ago... would have been US$0.52 from Sunset Imports...)

 

you should replace 2,3,21,22,26, 29 and 30 while you are doing this.
